To all whom it may concern:

Be it known that I, HARRY C. MALmRY a citizen of the United States, residing at Bellport, Suffolk County, in the State of New 5 York, have invented certain new and useful Improvements in Expansible Collapsible Elements, of which'the following is the full, clear, and exact specification.

My invention relates .to improvements in methods of making flexible or elastic elements adapted for use in connection with apparatus or devices, subject to or influenced by temperature or pressure variations, whereby to operate a valve or other ,ap-

paratus or mechanisms.

Further, said invention has for its object to provide a method of makin a flexible or elastic element to be interpose between two or more parts-of an apparatus or device certain of which are movable with respect to the other thereof, to form a flexible fluidtight joint yieldingly connecting said parts.

Further, said invention has for its object to provide an expansible-colla sible element of the character specified havmg means socured thereto whereby said element may be readily and efliciently secured to or within a;

valve or other part or device in connection with which the same is to be used.

Further,said invention has for its object to provide an expansible-collapsible element having-a supporting member secured thereto whereby said element may be readil and efficiently secured within a valve bo y or other device or art Further, said lnvention has for its object to provide an expansible-collapsible element having a supporting member which serves as a convenient means of attachment to a 40 valve casing, or other device or part, and having means for securing said element to said support which means also serve to reinforce said expansible-collapsible element. Further, said invention has for its object to provide an expansible-collapsible element having a supporting member secure thereto which serves to form a fluid-tight'jointat the junction of said parts, and also serves as a' means whereby the element may be 5 readily. attached to, or detached from a valve casing, or other device or part in connection with which the same is to be used or of which it forms a part.

Further, said invention has for its object to provide a simple, convenient and inexpensive method of producing an element of the character hereinabove specified.

Other objects will in part be obvious, and in part be pointed out hereinafteia.

To the attainment of the aforesaid objects and ends my invention consists in the novel details of construction, and in the combination, connection and arrangement of parts and in the several steps constituting the method hereinafter more fully described, and then pointed out in the claims.

In the accompanying drawings forming partof this specification wherein like numerals of reference indicate like parts,

Figure 1 is a central, vertical section showing one form of expansible-collapsible element, and supportingmeans therefor;

Fig. 2 is a similar now showing a modi-, fi'ed construction in which the end of the expansible-collapsible element is secured in position byan annular member which serves also to reinforce the end of said element and to render the joint at the junction of said parts fluid tight, and

Fig. 3 is a similar view illustrating a further modification in which the open end of the e'xpansible-collapsible element is socured wit in a support by the flanged portion of a c lindrical member or closure.

In said rawings 10 designates a support which is herein shown in the form of an annular member having its outer ed e screwthreaded at 11, and above sai screwthreaded portion with a shoulder 12. The inner side of said member 10 is provided with an annular roove 13. 14 denotes an expansible-colla slble element which is shown as cylin rical in form and provided with an open end 15, and ,a closed end 16 having a reduced projection or boss 17 extending therefrom, The open end 15 of the element 14: is preferably made of greater thickness than the remainder of the element in order to facilitate the. attachment thereofto a support or other part. The 100 body or intermediate portion of the elemerit-15 is eircumferentlally corru ated to form a series of corrugations or fol s 18.

- In order to secure the expansible-collapsi ble element to the support or'member 'it merely becomes necessary to insert the open end into the opening in the annular memher 10, as shown at Fig. 1, and then by means of a suitable die, or by pressure, expand or force an annular portion of the closed end '15 into the annular groove 13inthe side of said supporting member 10 whereby said parts will be firmly secured to ther.

.Hereupon the expansible-col apsible element may be inserted into the opening in a valve' casing or other device or part ang secured in position therein by means of 1 threaded portion 11 engaging with registering threa s in the cooperating part.

In the modified construction shown at Fig. 2,,the expansible element 14, and the supporting member 10 are substantially the same as illustrated and describedin connec-' tion with Fig. 1, except that in the present instance the element 14 is shown having its side wall and closed end of uniform thickness, and its cldsed end reinforced by a disk 14 secured within said closed end. The open end of said element posed within the opening in the support 10 is secured thereto bya separate annular an annular bead 21 member 20 havin orcing or expanding the formed therein b wall of said member 20, and the open end of the element 14: into the annular grodve 13 provided in the inner side of the opening in said support 10.

j In the construction illustrated-at Fig. 3 the parts are similarly secured together as shown and described in connection with Fig, 3, except that in this form the open end 15 of the expansible-colla-psible element 14 is closed by a member-22 of smaller diameter than the interior of the element 14 which extends into the same, and is provided at its open end with a flange 23 which isforced or expanded into-the annular'groove 13 of the support 1O by producing an annular head in the portion, of said element adjacent to its 0 end.

It wi of course be obvious that the providing of the annular support 10, 10* with screw threads illustrates only one form of attachment, and that the said support with theflexpansible element carried thereby may be. -secured in many other ways to, or within a'gco operating device or part,
